The Silicon Audio Model 203 Low Noise Accelerometer bridges the gap between traditional strong motion accelerometers and weak motion seismometers. The exceptionally large dynamic range of the instrument can eliminate the need for multiple sensors and applications which once required a broad-band seismometer paired with a strong-motion accelerometer can be addressed with a single Silicon Audio Low Noise Accelerometer.
